International Cooperation is very useful for space exploration and even the most important thing in International Space Station. Cooperation is much better than competition. I would like to see cooperation between more countries. The congress allows astronauts free to communicate with each other. It is a good start for cooperation. I think one day we will go to Mars, because this is where we always wanted to go. Mars is very far away from Earth and the journey would take a long time and be full of risks. Countries should cooperate to get there.
